A new experiment confirms that angular momentum conservation holds even when a single photon is split into two.

Researchers find that a photon can spend a negative amount of time in an excited atomic state while passing through a cloud of atoms ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

In dark photon events, the deposited energy in the ECAL typically falls below 4 GeV, with energy decreasing as the dark photon mass increases. Conversely, inclusive background processes exhibit ...

“It’s a molecularly perfect coating, which presents a uniform environment for the single-photon-emitting sites,” Hersam said.

Researchers, in a recent Physical Review Letters paper, introduce a new mechanism that may finally allow ultralight dark photons to be considered serious candidates for dark matter, with promising ...

Figure.1 illustrates the conceptual mechanism of dark-photon production via dark bremsstrahlung and its subsequent decay into invisible dark matter, forming the experimental basis for DarkSHINE, which ...

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Quantum technologies demand perfection: one photon at a time, every time, all with the same energy. Even tiny deviations in the number or energy of ...
